In-depth safety analysis
The extension requests permissions such as scripting, activeTab, contextMenus, and sidePanel. When activated, these allow it to read and modify the content of the current webpage in order to overlay measurement tools, capture dimensions, and provide a ruler UI. The use of storage and offscreen is common for saving settings and performing background calculations. For a screen measurement tool, this set of permissions is typical and expected to deliver its core functionality.
As with any browser extension that can access page content, users should be mindful of what data is collected. The developer declares that the extension collects personally identifiable information, user activity, and website content. While some website content may be necessary for measuring elements, the declared collection of personal data and browsing activity goes beyond what might be strictly required for a ruler tool. A careful user would review the privacy policy to understand how this information is used and shared.
The fact sheet shows a strong Maintenance & Ownership score (100%), meaning the extension is actively updated and vulnerabilities are likely addressed promptly. The weakest dimension is Publisher & Identity (60%), indicating less verified or transparent publisher information, which can make it harder to evaluate trustworthiness. Overall, the permissions are appropriate for the category, but the lower publisher transparency combined with the declared collection of personal data warrants a cautious approach.
AI-assisted analysis of the documented signals above (permissions, store data, privacy practices) — explains what they mean and the risks typical for this category. Not a hands-on test.
